m4v
What is a .m4v file?
video/x-m4v
M4V (.m4v) is Apple's variant of the MP4 container, typically holding H.264 video and AAC audio and sometimes carrying FairPlay DRM. Without DRM it is essentially an MP4 and plays in most players.
How to use a .m4v file
Use an example .m4v clip to test MP4/M4V demuxers, players, and M4V-to-MP4 handling.

- M4V: iTunes H.264 ClipThe clip as M4V: Apple's MP4 variant used by iTunes. Browser-playable; for testing M4V handling and M4V↔MP4 conversion.
- Container: M4VOne H.264 elementary stream wrapped in M4V. Every file in this group was produced from the SAME encode with a stream copy, so the compressed video bytes are identical and the container is genuinely the only difference. MP4 under Apple's alternative extension. Byte-identical structure; the extension exists purely so iTunes could distinguish video, and it is a good test of extension-driven format detection.
